POOL-BALL FRAME.

SPECIFICATION forming part of Letters Patent No. 484,562, dated October18, 1892.

Application filed March 25,1892. Serial No. 426,349- (llo model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM A. SWEET, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Pool-Ball Frames, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to frames used in setting up the balls in the gameof pyramid pool, as played upon a billiard-table.

My object is to produce a frame for setting up the balls, which is inthe nature of an improvement upon the one patented by me December 8,1891, No. 464,745, consisting principally in thatin this constructionmeans are provided for exerting separate pressure upon each of the ballsof the rear row, such pressure being also exerted simultaneously uponall of them, whereby I am enabled to set them up so that all of theballs are in close contact with each other, even though they may varysomewhat in size.

My invention consists in the several novel features of construction andoperation hereinafter described, and which are specifically set forth inthe claims hereunto annexed. It is constructed as follows, referencebeing had .to the accompanying drawings, in Which Figure l is a top planof the frame and ing the detail construction. Fig. 3 is a sectionalelevation of the rear frame-bar on line 00 m in Fig. 2. Fig. 4 is anelevation of one corner of the frame, showing its leg and ball support.

The frame proper consists of the side rails a, and the rear rail orcross-bar 17, arranged in the form of an equilateral triangle, and, ifdesired, the side rails may be provided with rearward extensionsa',connected by a rail-bar b. When so enlarged, the rail-bar is providedwith a central index or pointer 19", which when said bar is placedagainst the cushion with the index in line with the central diamond inthe cushion-rail will bring the front ball of the pyramid exactly uponthe spot. The cross-bar consists of a bar recessed longitudinally, as atc, and a cross-plate c, and both said bar and plate are perforated toreceive the pressure-plungers d. Each of these plungers consists of abody and tenon, and springs d are placed around the tenons between saidbody and plate 0'. This bar is also mortised longitudinally, as at e,and the side rails likewise, to receive the finger-bar m, insertedthrough the cross bar I) and through mortises m in the plungers, so thatby retracting said bar an all of the plungers can be also retractedsimultaneously to release the frame from the balls. The side rails andcross bars are secured together with wood blocks and screws n, as arealso the extensions ct and the rail 1).

It will be readily seen that each of the plungers exerts a separate andindependent pressure upon the ball with which it is in contact, and thatthey together exert a simultaneous pressure upon all of the balls in thepyramid, and that by this joint and several pressure all of thevariations in the size of the balls are taken up, and all of them arebrought into close contact and set up tight.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with the side rails and cross-bars connecting them,of pressure-plungers mounted in the cross-bar.

2. The combination, with the side rails and cross-bar connecting them,of pressure-plungers mounted in said bar and exerting ajoint and severalpressure upon the balls in the frame.

3. The combination, with the side rails and cross-bar connectingthem andthe pressureplungers mounted in said bar, of a finger-bar engaging withsaid plungers and adapted to retract them simultaneously.

4. In a pool-ball frame, the combination, with the crossbar, ofhorizontally-reciprocating pressure-plungers mounted therein.

5. In a pool-ball frame, the combination, with the cross-bar, ofhorizontally-reciprocat ing independently-acting pressure-plungersmounted therein.

6. In a pool-ball frame, the combination, with the cross-bar, ofhorizontaily-reciprocating independently-acting pressure-plungersmounted therein and means to retract them simultaneously.

7. The independent plungers mounted in the frame, each bearingindependently against its ball in the rear row of the pyramid and alladapted to be simultaneously retracted from the balls to release theframe [0 from the pyramid.

In witness whereof I have hereunto set my hand this 22d day of March,1892.

WM. A. SWEET.

In presence of- C. W. SMITH, HOWARD P. DENISON.
